Application filed July 3, 1920. serial No. 393,789.

T 0 all whom it may concern:

Be it known that we, Anvil) Gust-Arson and JAMns- H. lllUnPHY, citizens of the United States, and residents of Bonita, in the county of Molheur, and Portland, in the county of Multnonmh, respectively, State of Oregon, have invented certain new and use ful lninrovenients in Campers Steel Portable Folding Beds, of which the following is u specification.

This invention relutes to beds of the type adopted and intended for temporary use and for frequent w enibl-ing end disassembling and transportation as in camping; It ernbhdies a structure mode principally of steel and is so designed that the requisite strength and rigidity may be secured by the use of ports of minimum size and weight while flirnishing the user with. substantially all of the ease and comfort of an ordinary bed. It includes novel features of construe tion by which the flexible bed bottom, which.

mav include elasticity, is supi'yortcd under "proper tension to avoid sagging; a miniii'i'uni of ez'isily uttochuble and detachable ports. It avoids entirely the use of nuts and screws and other :losteminn means re unking tedious operations and suhsti quick detachable connections which pi cticolly requirenothinp;more than placingthe ports in proper relative position. The coni'ioctions are so :t'or ed howe m: th the parts are e ,;:en1l;)lc(;l. those is no p thot thov will. become loose or not open a desired; The easily detechai e sung nine ports are of such length and shape that they inuv fit together across the flexible bed botzit tom parallel to the end. bars or angle irons costings which is to be riveted or secured to t the bed ore; vised wi h ockets to make slip oint con,-

The flexible bed bottom 10 may be made of any suitobletabric but in steel wire fabnic is preferred and it of course may he made in any of the Well known'ways. It is preferable that the hedhottom shall have at capacity for lyielding'or giving forfthe comfo'rtflof the user and therefore in Fig. :1 a

series of coiledgsprings 11 are 'sho'wnas interposedloetween and connecting at intervols the fabric 10 and the transverse angle bar 12 at the head of the-bed. As shown oneend of e ochjspril g Passes through i hole or opening 13 in the horizontal flange 14 of. th angle bar 12 endis thus securely held. m lhe angle bar 12 has depending flange 15 at "right i angles to flange 14- and is preerubly Inedc oi'stfeel ondthus furnishes a continuous rigid connection for the end of the bed \lJOtl OII A similar tangle bar vlfi is used at the footof the bed having thellori zontolnflo-n'ge L7 to which t he fabric'of the bed bottom is secured through holes 18 and e downwardly extending flange 19. Two

castings 20 (see Fig. 3) are secured tothe undei 'surfoce of flange 14: of the end bar 12 negn the ends by screws or preferably rivets passing through the openings 21 in the casting and openings 22 in the flange and therefore constitute a permanent part ot the angle bar 12. End casting 20 has downwardly extending cylindrical socket23 (see i dotted lines Figs. 3 and 5) open at the bottom to receive the upper end of a tubular post or leg Qli'or supporting the bar 12 and consequently that end of the bed. The upper end of post 24 fits easily in the socket with a, slip joint and may be easily removedafter lifting the angle bar 12 but any weight on the bed in use simply tends to make the" Each connection more certain and sure.

lindrical socket 25 directed horizontally. toward the foot of the bed and adapted to re ceive in it the end of the upper section 26 of the tubular side rail 2?. There is a groove 'or'depression 28in the face of castin'g'2O across theopen end of socket 25 and a pin 29 extends through the end of section 26 of the side rail fitting in that groove when the end is in'slip joint connection with the socket thus preventing the side rail from turning in the socket. Since the casting and socket are rigid with the end bar 12 the s de rail can not turn without the turning of the entire bed." The side mire? furthermore extends downwardly at an angle to a point below the foot ofthe bed and any weight on r the bed in addition to the normaltension on.

the bed bottom tends to -force it home and-hold it there in' th'e socket connection tothe end bar and avoids any possibility of the connectionicoming loose and avoiding allnecessity for tasteniin'g'it otherwise. flh'e tubular side bars-27 are inade up of two sections 26 and 30 havi'ng 'quick detachable connez-tion at the inicildle so m the slip oint i." 7: 1

The purpose of this iiiliendingis to make the end oi": bar 36st and grip the downwardly finclined cylindrical projection 4L0 Jon the casting ll which is Socured to the angle bar 16 at the toot of the lied. The casting ll. preferably hasiside flanges with holes 42 therein and through t se holes is bolted or preferably riveted 'to the flange 19 of the end bar 16. The

casting ll may furthermore have in it a slot through which a flexible connection ch as a strap 4A may extend and that an may extend down to the lower end of side rails and make connection there through a link l5.v The purpose and tion of thisstrap is of course toexert 1S .ower ends of the. side rails together and the sug pleinental bars to put tension on and keep tight the flexible bed bottom; It should be understood however that the pres- ;ent invention is not limited. to the particular means for connecting the angle har the 7 foot oi the lied. to the side railssince vai te ion to pull the angle bar 16 and the i own in 9 so-as so closely fit the part 36; At its upper or forward rious means for doing this adjustahlv to vary the tension at V skilled in the art.
